Abstract

A kind of polymerizable dispersant based on natural rosin was used to disperse single-walled carbon nanotubes (SWNTs) in aqueous solution followed by in situ free-radical polymerization to achieve a controllable SWNTs dispersion, that not only can be controlled by CO₂/N₂, but can also be recycled and redispersed in CO₂-saturated water after drying without sonication.
